β-半乳糖苷酶,是一种糖苷水解酶,可水解半乳糖与其有机部分之间形成的 β-糖苷键。在大肠杆菌中,lacZ 基因是 β-半乳糖苷酶的结构基因,可作为诱导系统lac 操纵子的一部分。β-半乳糖苷酶可以水解乳糖形成葡萄糖和半乳糖,进入糖酵解;也可以催化乳糖转半乳糖基化为异乳糖;异乳糖可以裂解成单糖。
应用
Lactozym Pure 适用于各种乳制品,包括鲜奶、UHT乳品(超高温灭菌奶)、乳饮料、奶油、冰淇淋、酸奶。更高的制剂纯度也提高了UHT工艺中的过滤性。
β-Galactosidase, a glycoside hydrolase, breaks down β-glycosidic bonds in galactose and its derivatives. In E. coli, it is encoded by the lacZ gene, playing a crucial role in the lac operon induction system. This enzyme not only converts lactose into glucose and galactose for glycolysis but also facilitates the transgalactosylation of lactose into allolactose, which subsequently breaks down into monosaccharides.
